Exchange Link Contacts

Hi everybody,
I have some questions about Exchange Link
are contacts stored when SLX is integrated with Outlook? Are they part of the Global Address Book or is a separate group?
I will appreciate your comments or answers about these questions.
Regards,

Yes, they are - they are copied from SalesLogix to Exchange and then E/Link
will keep them in-sync after that. The GAL is not used (in a sense) - a new
sub-container is used per user (you define this when you setup the link).
